RCG Racing Tracer / MT-One 鋼製機器差速器 含金屬杯 (升級件)

Dropped these into my MT-One and the fit is spot on—the metal cups slide onto the shafts with zero play, which is exactly what I wanted for racing. They feel noticeably tougher than the stock bits, and the whole diff runs smoother under load.

The metal cups feel properly machined and lock onto the output shafts without any slop. Dropped these into the diff housing and the whole assembly spins smoother than the stock plastic unit ever did.

The machine cut diff gears mesh perfectly with my existing drivetrain, and the included metal cups add a nice weight that improves handling. Installation was straightforward for anyone familiar with RC maintenance.
